Abstract

Background: Balanced nutrition education is an essential effort in preventing obesity, especially in adolescents who are vulnerable to nutritional problems due to unhealthy diets and a lack of knowledge. This study aims to determine the effectiveness of Android-based e-pocket books in improving the understanding of balanced nutrition among adolescents in Yogyakarta. Methods: This study employed an experimental design with control groups, utilizing pre-tests and post-tests. Conducted from February to March 2023 in a high school in Yogyakarta, Indonesia, the research established a minimum sample size of 27 students per group through the Lemeshow formula and multistage sampling. Inclusion criteria required students to have Android phones, to consent to participate, to attend the study, and to complete data collection. The treatment group received education via e-pocket-book media, while the control group used e-leaflets. Knowledge was measured at three points: before the intervention, immediately after (post-test 1), and nine days later (post-test 2). Data analysis was performed using the Wilcoxon and Mann-Whitney tests with SPSS software. Results: The knowledge score of the treatment group increased from 76.3 (pre-test) to 93.8 (post-test 1) and 91.3 (post-test 2). The control group increased from 73.8 (pre-test) to 82.5 (post-test 1) and 81.3 (post-test 2). The increase in knowledge was more significant in the treatment group, showing that e-pocket-books were more effective than e-leaflets. Conclusion: Android-based e-pocket-books improve adolescents' knowledge of balanced nutrition more than e-leaflets. Digital technology in nutrition education has great potential to be applied in schools. Further research is needed to evaluate the long-term impact on nutritional behavior.

Abstract

Rectosigmoid cancer patients undergoing chemotherapy are at high risk of malnutrition due to metabolic alterations and treatment-related gastrointestinal side effects. Evidence on the implementation of standardized nutritional care in primary healthcare settings remains limited. This study aims to evaluate the provision of standardized nutritional care with a diet high in energy and protein and its impact on the intake, nutritional status, and clinical condition of rectosigmoid cancer patients undergoing chemotherapy. The case was a 50-year-old male with stage III rectosigmoid cancer undergoing chemotherapy, who presented with undernourished status, diarrhea, reduced appetite, dysphagia-related discomfort, and anemia. Nutritional assessment identified inadequate oral intake and increased energy and protein requirements. Standardized nutritional care was implemented using the Nutrition Care Process (NCP) framework, including an individualized high-energy, high-protein (HEHP) diet and nutrition education for the patient and family. Dietary intake was monitored over three consecutive days using 24-hour food recalls. The patient demonstrated improved tolerance to oral intake, increased protein consumption, stabilization of body weight, and no worsening of gastrointestinal symptoms during the intervention period. This case illustrates that standardized nutritional care using a high-energy, high-protein diet can support dietary intake and help maintain nutritional status in rectosigmoid cancer patients undergoing chemotherapy, even in a primary healthcare setting. Early and individualized nutritional intervention may play an important role in preventing further nutritional deterioration and supporting comprehensive cancer care.
